HAROLD J. BRADT, OF ROCHESTER, MICHIGAN.

DISK-WHEEL HUB CONSTRUCTION.

Application filed July 27,

To all whom it may concern:

Be it known that I, HAROLD J. BRADT, a citizen of the United States of America, residing at Rochester, in the county of Oak-.

land and State of Michigan, have invented certain new and useful Improvements in Disk-VVheel Hub Constructions, of which the following is a specification, reference being had therein to the accompanying 1 drawings.

This invention relates to a disk wheel hub construction and has special reference to that class of wheels of the single disk type having any form of rim or tire, and a hub construction which permits of the hub member being securely attached to the disk of a wheel.

One of the objects of my invention is to provide, as a new article of manufacture, a

metallic hollow filler member that may be easily and quickly installed to assist in supporting a hub relative to a disk, the filler member being interposed between the disk and the fixed flange of the hub to hold the disk against-a detachable flange.

' A further object of my invention is to provide a hub construction for a disk wheel wherein a filler member presses the disk of the wheel, relative to the hub and reduces to a minimum stresses and strains on the center portion of the disk which might set up a shielding action or cause fracture of the disk.

The above are a few of the objects attained by my hub construction and others will appear as the nature of the invention is better understood.

Reference will now be had to the drawing, wherein Figure 1 is a vertical sectional view of the hub construction in accordance with my invention;

Fig. 2 is a detail sectional view illustrating a modified form of filler member, and

Fig. 3 is a similar view illustrating an 1923. Serial No. 654,123.

central inwardly turned collar 7 to receive the hub member 1. In addition to this collar there are openings 8 for the bolts 4.

Between the disk wall 6 and the fixed flange 2 is a hollow metallicfiller member comprising a flange engaging wall 9, a rim 10 and a conical portion 11, said conical portion being disposed concentric of the rim 10 and tapering inwardly towards the axis of said filler member. The conical portion 11 engages the disk wall 6 at its juncture with the collar 7 and said conical portion has an inturned collar 12 fitting on the collar 7. hen the filler member is clamped against the disk wall 6 any tendency of the filler member to flatten but causes the collar 12. thereof to more firmly bind against the collar 7 and the same result is obtained by providing a rim 10 with a peripheral edge portion 13 which binds against the disk wall 6 opposite the peripheral edge of the detachable flange 3. \Vith the overall dimension of the filler member greater than that of the detachable flange 3 the disk 5 is well braced at the eripheral edge' of the detachable flange an revents any shearing action of the disk re ative to said flange.

In some instances the conical portion 11 of the filler member may simply bear against the disk wall'6, without engaging the collar 7 as shown in Fig. 2, and in other instances, the disk wall 6 may be provided with pressed out portions 14 to engage in corresponding portions 15 of the filler member, as shown in Fig. 3. The inter-engagement of the disk wall 6 with the filler member will correctly osition said filler member relative to the isk by alinin bolt openings 16 of the filler member with the bolt openings 8 of the disk wall 6. The disks and filler members will be prevented from circumferentially creeping relative to each other.

I attach considerable importance to the fact that the filler member may be stamped and pressed from sheet steel and by engaging the disk at two circumferential places, one concentric of the other, the central portion of the disk is firmly anchored between the flanges of the hub member.

I do not care to limit my invention to the contour of the disk 5, other than at the hub ortion, and while in the drawing there is illustrated the preferred embodiments of my invention, it is to be understood that the structural elements are susceptible to such changes as fall within the scope of the appended claims.

What I claim is 1. In a disk wheel, a hub construction including a hub having a fixed flange, a detachable flange, a disk engaging said de- 2. In a disk wheel, a hub construction.

including a hub having a flange, a disk engaging said hub, and a filler member having a conical portion said filler member engaging said disk opposite inner and outer marginal portions of said flange.

3. In a disk wheel, a hub construction including a hub having a fixed flange, a detachable flange, a disk engaging said detachable flange, a hollow filler member between said disk and said fixed flange, and means extending through said flanges, disk and filler member for holding said elements together, said disk having a pressed out por tion engaging in said filler member to correctly position said disk relative to said filler member.

4. As a new article of manufacture, a filler member for a disk wheel hub, comprising a wall having a rim and a concentric conical portion, the rim having an outstanding disk engaging edge portion and said conical portion having an inturned collar.

5. In a disk wheel wherein a disk has a flat portion engaging a hub flange and a curved portion extending away from the peripheral edge of said flange ;-a member for bracing said disk at said flange, said member having an annular portion disposed at a right angle to said disk and an edge portion bracing the curved portion of said disk adjacent said hub flange.

6. A disk wheel construction including a hub having flanges, a disk against one of said flanges, a filler member engaging said disk opposite inner and outer marginal portions of one of said flanges, and means connecting said flanges, disk and filler member together.

In testimony whereof I aflix my signature in presence of two witnesses.

HAROLD J. BRADT.
